[ausev] [Aceaa] interesting GE DC motor on Ebay

[m. howse]

Hello all,

Yes, there's a lot to be said about experience. Knowledge and experience  
is certainly
better, usually, but in the case of conversions there can be many more  
variations that
require imagination and patience also and more likely a major amount of  
perseverence.
One of the aspects of advice that always concerns me though is the bias  
that sometimes
creeps into the issues. Not that bias is necessarily bad in this case but  
it is not
always the best option. For example, some seem to think that high voltage  
motors are
better and on this I disagree. I have three motors I plan on using in  
different
vehicles, one is 36 volt, one is 48 volt and one is 240 volt and I can  
guarantee
that 24kw is 24kw whether it is with a 24 volt motor or a 240 volt motor.
I do think that as much heart as knowledge is required, though. And I would
also inject that making mistakes is not necessarily bad as long as they  
are not
the last mistake you'll make.
just my .5kw worth
